There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ \frac{({L}^{2} + 4{x}^{2})}{(8x)}\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = \frac{\frac{1}{8}L^{2}}{x} + \frac{1}{2}x\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( \frac{\frac{1}{8}L^{2}}{x} + \frac{1}{2}x\right)}{dx}\\=&\frac{\frac{1}{8}L^{2}*-1}{x^{2}} + \frac{1}{2}\\=&\frac{-L^{2}}{8x^{2}} + \frac{1}{2}\\ \end{split}\end{equation} \]
